PASTING APPARATUS.

Specification of Letters Patent.

Patented Dec. 21, 1915.

Application filed July 12, 1915. Serial No. 39,438.

To all whom it may concern:

Be it known that I, WARD B. DUNLAP, a citizen of the United States,residing at Delaware, in the county of Nowata and State of Oklahoma,have invented certain new and useful Improvements in Pasting Apparatus,of which the following is a specification, reference being had to theaccompanying drawings.

This invention relates to an improved pasting apparatus and has for itsprimary object to provide a machine for this purpose which is primarilydesigned for applying paste to wall paper whereby the papering of wallsmay be greatly expedited.

It is one of the more particular objects of the invention to provide animproved mounting and construction of paste container and means arrangedtherein for uniformly applying the paste to the paper.

The invention has for an additional ob ject to provide means forremoving the surplus paste from the paper and an improved mounting for arotary cutter knife, whereby the paper drawn from the roll may besubsequently cut in sections of the desired length.

. The invention has for still another object to provide means fortrimming thepaper, and operating said trimming mechanism eithersimultaneously with the pasting device or independently thereof.

It is a further general object of my invention to improve and simplifythe construction of paste applying machines of Y the above character,whereby the same may be very easily and quickly assembled and arrangedin condition for use, the machine, as a whole, consisting ofcomparatively few parts which are positive and reliable in theiroperation.

With the above and other objects in view, my invention consists in thenovel features of construction, combination and arrangement of parts tobe hereinafter more fully described, claimed and illustrated in theaccompanying drawings, in which,

Figure 1 is a side elevation of a paste applying machine constructed inaccordance with the preferred embodiment of my invention; Fig. 2 is afront elevation thereof;

- Fig. 3 is a longitudinal section; and Fig. 4

is a detail perspective view of the cut off knife and the supporttherefor.

Referring in detail to the drawing, 5 designates two parallel side wallswhich are connected together and held in spaced relation by'a pluralityof transversely extending rods or bolts 6. The side walls 5 are alsoprovided at their opposite ends with the spaced upper and lowerlongitudinally projecting arms 8. Each side wall is further providedwith a central longitudinally extending slot 9 which opens at its outerend between the spaced arms 8. The container or receptacle for thepaste, shown at 10, is preferably cylindrical in form and arrangedbetween the spaced side Walls .5. This conbrush is provided atitsopposite ends with.

trunnions 16 which are journaled in bearing plates 17 arranged upon theouter faces of the plates 5 and extending vertically across the'slots 9said faces. The opposite ends of the caring plates 17 are sooured to theplates 5 by suitable screws 18. It will be understood that the trunnions16 on the ends of the rotary brush project outwardly through the slots12 in the end walls of the container 10, and one of these trunnions hasa large gear wheel 19 fixed thereon, the extremity of said trunnionbeingof rectangular form to receive the socket of a suitable crank 20,whereby the brush may be manually rotated. The bristles of the brush 15project outwardly through the opening 11 in the side wall of thecontainer, and at the upper side of this opening opposite to the tubularbead 13, a guard plate 21 is hinged, as at 22, upon the container wall.Additional vertical bearing plates 23 are also secured upon the outerfaces of the arms 8 on each of the side plates 5, and in these bearingbars the trunnions 24: on the ends of the lower roller 25, arejournaled. One of these trunnions has a gear wheel 26 fixed thereonwhich meshes with a power transmission gear 26""journaled upon a stubshaft 26 secured in the side plate 5, said transmission gear alsomeshing with the gear 19. Thus, the rotary brush and the roller 25 arerotated in the same direction.

has a similar slot 29 formed therein.

Through theseslots, the trunnions 30 on the ends of the upper roller 31are disposed. In the upper end of each of the arms 27, a. vertical rod32 is slidably engaged, the lower end of said rod being provided withthe bearing block 33 for engagement upon one of the roller trunnions 30.A spring 34 is arranged upon said rod between the upper end of the arm27 and said bearing block. Upon the rod 32, a nut 35 is threaded, and byadjusting this nut, the tension of the spring 34 may be regulated, asdesired.

To each of the vertical bearing bars 23, and centrally thereof, aforwardly projecting arm 36 is secured. The forward end of each of thesearms 36 is provided with a socket to receive one end of a transverselydisposed bar ,37. A longitudinally extend;

ing kerf 38 is cut in the upper face of this bar and a metal plate 39 isalso countersunk in the upper face of the bar at the outer edge of thekerf 38. A wire rod 40.

extends in longitudinal parallel relation to the bar 37 above the sameand has itsends angularly bent, as at 41, and the extremities thereofturned inwardly and en aged through openings in the arms 36 and ttinginto sockets formed in the ends of the bar 37.

42 designates a rotary steel cutting disk adapted to travel in the kerf38. This cutting disk is journaled upon an axle pin 43 fixed in thelower bifurcated end of a vertically disposed bar 44. This bar is formedwith an opening through which the rod 40 is loosely engaged and said barmay be readily shifted longitudinally upon the rod and the cutting disk42-moved along the guide kerf 38.

When the parts are assembled or arranged 'in position between the sideplates 5, the curved guard plate 21, which is hinged upon a wall of thepaste container 10,.ex-

tends over the upper roller 31 substantially in concentric-relationthereto, suitable stop lugs or supports 45 being fixed to the innerfaces of the side walls 5 upon which this guard plate is adapted torest.

In conjunction with my improved pasting apparatus, I provide means fortrimming the paperas it is drawn from the roll. To this end, uprights orstandards 46 are securedto thev rear ends of the side walls 5 andbetween the same the two rollers 47 and 48 are rotatably mounted. Thebearings for the lower roller 48 are stationary while the upper roller47 is vertically movable between the standards and is yieldingly heldagainst such vertical movement by the springs 49 which are mounted in asimilar manner to the springs 34 of the roller31, above referred to.Each of the rollersi47 and 48 has a cutting ring or annulus 50 fixedthereto adjacent one of its ends, and

the cutting ring on one roller operates in the annular groove 51 in theperiphery of the upper roller and cooperates with the cutting ringon thelower roller to produce a shear cut of the paper as it is drawn betweenthe rollers. The upper edges of the spaced walls 5 are connected byparallel barsor ribs 52, and these ribs are received in notches,indicated at 54, in the lower faces of the cleats 53. These cleats areconnected by spaced slats 55 upon the opposite ends of which the bearingmembers 56 are secured. In these members, the gudgeons of a paper roll Pare journaled. In the upper ends of the uprights 46, the ends of arectangular roller '57 are removably mounted, and upon this roller thetrimmed paper is adapted to be wound when the pasting mechanism is notbeing used. Upon one end of the shaft of the roller 57 a belt wheel 58is fixed, and a similar wheel indicated at 59 is also secured upon oneend of the shaft of Qhe lower roller 48. This wheel isadapted-to beconnected bv a crossed driving belt 60 to the belt wheel 61 which isfixed upon one end of the brush shaft. When it is desired to operate thetrimming mechanism independently of the pasting device, the wheels 58and 59 are connected by a power transmission belt 62. One end of theshaft of the lower roller 48 is square so that the crank 15 may bereadily applied thereto.

the paper from the roll P is drawn between the trimming knives 51 on therollers 47 and 48 and then extended forwardly beneath the container10,'as clearly shown in Fig. 3, and

upwardly over the lower roller 25 so that the paper will be engaged bythe brush 15. The bristles of the brush projecting through the opening11 in the container wall willcontact with the paper sheet. It will beunderstood that the crank 20, as it is turned, rotates the pasting brushand rotation is also transmit ted through the medium of the belt 60 tothe roller 48. The peripheries of the rollers 47 and 48 are engaged sothat the paper is fed thereby to the machine and, at the same time, iscut or trimmed by the knives 51. The spring pressed upper roller 31bears upon the paper sheet an d operates in conjunction with the lowerrelatively stationary roller 25 to remove the surplus paste from thepaper. The curved guard plate 22 prevents this paste being carried uponthe 'periphery of the roller 31 and thrown for per face of-the bar 3 42on the rod 40, saiddisk cooperating with the edge of the metal late 38and the upg to cleanly cut the paper. When it isno longer desired to usethe machine, the brush 15 is removed so that the paste will not dry uponthe brush bristles and render the same stifi and unfit for subsequentuse. This removal is readily accomplished by simply detaching thebearing plates 17 from the side walls 5 of the machine and then shiftingsaid roller forwardly through the opening 11 in the wall of thecontainer 10. It is, of course, understood that the rollers 25 and 31must first be removed from the side plates of the machine before it ispossible to remove the brush. If desired, the side plates 5 may also bedisconnected, and the entire machine very compactly arranged forconvenience in transporting the same from place to place. The apparatusas a whole is positive and reliable in its operation and provides Veryconvenient and serviceable means for facilitating the application ofpaste to wall paper. It is, of course, understood that the brush, aswell as the rollers 25 and 31, will be of somewhat greater length thanthe width of the wall paper, as this width, after the paper has beentrimmed, will vary to a greater or less extent. It will also be notedthat, while I have shown and described the preferred construction andarrangement of the several elements of my invention, the device issusceptible of considerable modification therein and I, therefore,reserve the pzivilege of resorting to all such legitimate changes as maybe fairly embodied within the spirit and scope of the invention asclaimed.

Having thus fully described my invention, what I desire toclaim andsecure by Letters Patent is 1 1. A paper pasting machine including apaste container vhaving a longitudinal openin a rotary brush mountedwithin said contalner, the bristles of the brush projecting outwardlythrough said opening, and means arranged adjacent to said openingexteriorly of the container to positively pull a paper sheet over theexterior surface of the container wall and past the opening therein forcontact with the bristles of the rotary brush.

2. A paper pasting machine including a paste container having alongitudinal openmg in its wall, a rotary brush mounted within thecontainer, the bristles of said brush extending through said slot, paperguiding and feeding means arranged contiguous to said slot exteriorly ofthe container and adapted to draw a paper sheet around the base portionof the container in contact with the wall thereof, and past the slot inthe container whereby paste is applied thereon by the bristles of thebrush, and guard means on the container wall adapted to be positionedwith respect to said guiding and feeding means.

3. A paper pasting machine including spaced side plates, a, pastecontainer mounted between said side plates having a longitudinallyextending opening and slots in its end walls communicating with saidopening, a rotary brush removably mounted within the container, upperand lower rollers mounted contiguous to the longitudinal opening .in thecon-tainer, said roller being vertically movable, a guard plate arrangedupon the container wall at one side of said longitudinal opening, apaper roll support,

the paper being extended from the roll between said rollers, said guardplate extending forwardly over the vertically movable roller, andgearing for positively rotating the brush and said lower roller.

4. A paper pasting machine including spaced parallel side plates, acylindrical paste container having a longitudinal opening in its walland a tubular head at one edge of said opening, a fastening -rodextending through said bead and the side plates, a guard plate hingedupon the wall of the container at the other edge of said opening, arotary brush mounted within the container, the bristles of the brushprojecting through said opening, upper and lower rollers mounted betweenthe side plates forwardly of the container and contiguous to the openingtherein, said guard plate projecting forwardly over the upper roller,the paper extending beneath the container and upwardly and forwardlybetween said rollers, and gearing positively rotating the brush and thelower roller.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.
